WELL-PUMPING MECHANISM.

Specification of Letters Patent.

Patented April 27, 1909.

Application filed June 17, 1908. Serial No. 438,968.

a resident of Parkersburg, in the county of Wood and State of VestVirginia, have invented certain new and useful Improvements inell-Pumping Mechanism, of which the following is a. specification.

The primary objectof this invention is to provide an improved adjustableconnection between the walking beam or other pump reciprocating meansand the connection lead ing to the pump, a wire cable being her shown asforming such connection, the main purpose being to preserve all of theadvan tages incident to the adjustment of the ordinary temper screw, andat the same time relieve the connecting threads of the adjustable partsfrom the load and prevent stripping.

A further purpose is to rigidly unite the parts after they have beenadjusted as required, and prevent that adjustment from being disturbedby the strains or stresses incident to the pumping operation.

The invention is designed primarily for use with a wire cable instead ofthe pump or sucker rods ordinarily employed, although it is notnecessarily confined to this use.

Such an adaptation of the invention is shown. in the accompanyingdrawings, Figure 1 being an elevation thereof, broken and partly insection. Fig. 2 is a sectional view on a larger scale of the adjustableconnection, and Fig. 3 is a sectional plan, enlarged, of the clamp.

Referring to the drawings, 2 designates a portion of a walking beam,which is the pump reciprocating means here shown, and 3 is the pumpingcable which depends into the well tubing 4t, with a socket 5 secured tothe lower end of the cable for uniting either directly with a pump, orwith an interposed sinker bar 6, a portion of which is shown in Fig. 2.

The improved connection between the beam and the pump-operating cablecomprises two parts or members, one adjustable longitudinally within theother. In the present adaptation, one of these parts consists of thetubular hanger or support 7, having the T-head 8 at its upper end forconnecting with the beam in the usual manner. Interposed in the lengthof tube 7, preferably shown, and in which there is preferably only:-ruliicient vertical area of threads to take the necessary hold on thethreaded upper extremity 10 of rod 10 which depends from rod 7.

Secured to tubular portion 7, preferably at the lower extremity thereof,is the clamp head 11, having a passage tor rod 10, and also providedwith the transverse slideway 12 in which-operates slide 13. The slide isalso provided with a passage 15 through which the rod extends, and inthe present adaptation one end 15 of the slide is extended through thehead and threaded to receive a nut 16, which operates to draw the slideoutwardly and so bind the rod as to form a rigid connection between thelatter and tubular support 7. Passage 1:4 in the slide is preferablyother than round, with the portion 1% which moves against the rodcontracted so as to wedge against and bind the rod, and thereby rendermore effective the clamping connection. lVith the rod passage formed inthis way, together with the direct outward pull or draw ob tained byturning up nut 16, a powerful and most secure clamping action results.

At the lower end of rod 10 is T-head 17, and immediately therebeneath isswivel18 with which the members of the cable clamp 19 are connected byrings 20. WVith slide 13 relaxed, rod 10 may be rotated by head 17 andthereby either raised or lowered,

within the tubular support 7 as the adjustment of the pump may require.When this adjustmentis attained, slide 13 is operated to clamp rod 10,as above described, whereby the weight of the rod is borne directly bythe clamp, thus relieving the threaded connection, and at the same timepreventing the adjustment from shifting or loosening under theconsiderable operating strains'ol the mechanism, an objection incidentto the ordinary temper screw connection.

While the improvement is shown and described in connection with pumpingmechanism, it may be used in any other connection and for any otheroperation to which it may be adapted.

The improvement is preferably employed in connection with an oil savingdevice of the form shown in Letters Patent No. 818,7 410, granted to meApril 24, 1906, wherein the cable is clamped at 21 to the upper end ofthe oil-saver tube 22, as in the above men tioned patent, said tubereciprocating through stutling box 2 secured to the upper end of thewell tube By this means, the escape of oil upwardly around the cable isprevented. that the invention may be used with other forms of oil.savers, or without sueh a device at all, as may be desired.

1 claim l. The combination of a tubule. provided with internal threadsabove. its lower end andv at its upper end adapted to connect with thepinup reciprocatingmeans, v

a rod entered in and depending from tubular member and its upper endthreaded for adjustment vertically through the threaded portion of thetubular member with pump conneeting means secured to the lower end oithe rorb and rod clamping mean carried by the tubular member beneath thethreads of the la 'ter tor eng member t the unthreaded portion of therod and thereby PQ-t'llllltll' together the rod and tubularmemberiudependeutly of said, threaded couneetion.

2. In well pumping apparatus, a loilgltudmally adpistable connectionoetween the pump reeiproeating' means and the pumping cable, saideonnectum consistingof a 1 support and a rod threaded to and dependmgfrom the support, a swivel at the lower end of the rod, a cable clampsecured to the it will be understood however I swivel, and meansseparate and apart from the threads of the rod tor uniting the rod andsaid support and relieving the threads of stripping strains.

o. In well pumping apparatus, alongitudinally adjustable connectionbetween the pump reciprocating means and .the pumping cable, saidconnection consisting in part of a threaded rod, a swivelcable-connection at the lower end of the rod, a tubular member intowhich the threaded rod extends, an inua'nally threaded part in thelength of the tubular member engaged by the threads of the rod, means atthe upper end of the tuhula r member for connecting with the pumpreeiproeating' means, and a clamping device carried by the tubularmember for engagin and holding the rod independently of the threadsthereon.

in testimony whereof I afiix my signature in presence of two witnesses.
